SPECIFICATION forming part of Letters Patent No. '7 50,607, datedJanuary 26, 1904.

Application filed September 21, 1903. Serial No. 174,013. (No model.)

To all whmn, it WWI/Z] concern.-

Be it known that I, EVERETT (1001:, a citizen of the United States, anda resident of Portland, in the county of Cumberland and State of Maine,have invented a new and Improved Boiler-Brace, of which'the following isa full, clear, and exact description.

The object of the invention is to provide a new and improvedboiler-brace which is simple and durable in construction, cheap tomanufacture, readily applied, and arranged to prevent the boiler-headfrom bulging outwardly and loosening the joints of the tubes in thehead.

The invention consists of novel features and parts and combinations ofthe same, as will be more fully described hereinafter and then pointedout in the claims.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all ofthe views.

Figure 1 is a transverse section of the improvement as applied, thesection being on the line 1 1 of Fig. 2. Fig. 2 is a longitudinalsectional elevation of the same on the line 2 2 of Fig. 1, and Fig. 3 isa perspective view of the improvement.

The body of the boiler-brace is made from a single piece of sheet metal,and it consists of a ring-section A, angular flanges B, extendingintegrally from the outer edge of the ring-section A, and a spherical orarched central portion C, extending integrally from the inner edge ofthe ring-section.

The ring-section A of the body is secured by rivets D to the head E ofthe boiler, and the longitudinal terminals of the angular flanges B arefastened by rivets D to the shell F of the boiler, and the spherical orarched portion C is connected by stay-rivets D to the boilerhead E.

The brace described is arranged in the upper portion of the boiler abovetubes G, and the lower edge of the brace-body extends approximatelydiametrically of the boiler-head, as plainly shown in Fig. 2, so that anexceedingly strong brace is produced connecting the head E with theshell F to prevent outward bulging of the head, and thus maintain thejoints of the tubes G in the head E at all times in proper condition toavoid leakage. It will further be seen that by the arrangement describedeach flange B forms a brace between the head E and the shell F, and byhaving the flanges arranged as described sufficient room is left at theend of the shell adjacent to the head E to accommodate the inner headsof the rivets H used for connecting the head to the shell F. (See Fig.2.)

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A boiler-brace made of a single piece of materialand comprising a ring-section for attachment to the head of the boiler,angular flanges extending integrally from the outer edge of the saidring-section and arranged for engagement with the shell, and a sphericalcentral portion extending integrally from the inner edge of the saidring-section, as set forth.

2. The combination with a boiler,of a boilerbrace extending between thehead of the boiler and the shell thereof, in the upper portion of theboiler, the said boiler-brace being made of a single piece of materialcomprising a ringsection for attachment to the head of the boiler,angular flanges extending integrally from the outer edge of the saidring-section, to engage the said shell, a spherical central portionextending integrally from the inner edge of the said ring-section andprojecting from the inner face of the head, fastening devices forconnecting the ring-section and the spherical central portion to theboiler-head, and fastening devices for securing the flanges to theshell, as set forth.

3. The combination with a boiler, of a boilerbrace extending between thehead of the boiler and the shell thereof, in the upper portion of theboiler, the said boiler-brace being made of a single piece of materialcomprising a ringsection for attachment to the head of the boiler,angular flanges extending integrally from the outer edge of the saidring-section, to engage the said shell, a spherical central portion ex-I tending integrally from the inner edge of the In testimony whereofIhave signed my name said ring-section and projecting from the into thisspecification in the presence of two subner face of the head, rivets forfastening the scribing Witnesses.
